Abstract
554,467. Automatic regulation. HARMER, H. M. Oct. 28, 1941, No. 13856. [Class 38 (iv)] A constant D.C. voltage is obtained from a single phase current supply by connecting two inductive reactances T 1 , T 2 in series across the supply one of which T 2 is cored with iron or magnetic alloy and run saturated and is in parallel with a capacitive reactance C the inductance and the other reactance being made to increase when the supply voltage increases and vice versa by a rectified current developed by windings n 1 , n z on the two inductive reactances which are series connected and mutually reversed in phase and supplying a saturating winding such as mA. The several reactances are so related as to give an external capacitative reactance value and the voltages across the inductive reactances have a polyphase relationship ; these voltages are then rectified and applied to the load circuit R, for example by a Scott connection as shown in Fig. 4. Twin magnetically balanced inductances may be used for the inductance T,. A barretter may be paralleled across the A.C. input or the D.C. output of the rectifier providing the saturating current and a rheostat RA may be included for adjustment. A separate circuit comprising elements similar to T 1 , T 2 , C may be used to obtain the saturating current. Specifications 493,362, 515,207 and 524,565 are referred to.
